Description

Technical Field

[0001] The present application belongs to the technical field of automation equipment, and in particular relates to a liquid chlorine purity analysis device and a control method thereof. Background Art

[0002] At present, when common chlorine analyzers analyze the purity and moisture data of chlorine, chlorine that does not meet the requirements and chlorine that meets the requirements will be discharged through the same exhaust port, making it difficult to achieve the classified collection of chlorine. At the same time, during use, the chlorine analysis components are not easy to disassemble and replace, and the maintenance and use costs are high.

[0003] The existing Chinese patent, with publication number CN219573613U, discloses a closed liquid chlorine sampling device, relating to the field of sample sampling technology. The closed liquid chlorine sampling device includes a liquid chlorine sampler, a sampling port, an inlet pipe, a bypass pipe, and an emergency chlorine pipeline. The liquid chlorine sampler is provided with an outlet and an inlet at the top and bottom, respectively, with an air extraction valve provided at the outlet and a sampling valve provided at the inlet. The bypass pipe is connected to the inlet pipe and the emergency chlorine pipeline at both ends, and the bypass pipe is provided with a bypass valve. The emergency chlorine pipeline is connected to the outlet via the air extraction valve. The inlet pipe is connected to the inlet via the sampling valve, and a sampling port is provided at the end of the inlet pipe away from the inlet. The sampling port is provided with a bottom valve located between the sampling port and the bypass pipe at the connection point of the inlet pipe.

[0004] Although the above analysis system can realize the analysis of the purity of liquid chlorine, the device occupies a large space and the process from the sampling port to the sampler is long, which is not conducive to the timeliness of the detection. Summary of the Invention

[0005] The purpose of this application is to address the above-mentioned technical problems and provide a liquid chlorine purity analysis device and a control method thereof, which can continuously perform purity analysis and monitoring on the liquid chlorine flowing in the delivery pipeline with high detection accuracy.

[0006] The present application provides a liquid chlorine purity analysis device, comprising a delivery pipeline for delivering purified liquid chlorine, the delivery pipeline comprising:

[0007] A mounting base, installed on the conveying pipeline;

[0008] An extraction mechanism is mounted on the mounting base;

[0009] An analysis chamber is placed on a mounting base;

[0010] an analyzer, installed in the analysis chamber;

[0011] Among them, the extraction mechanism includes an extraction seat, an extraction chamber, and an extraction piston. The extraction chamber is placed on the extraction seat. The extraction piston is placed on the extraction seat and corresponds to the extraction chamber. The extraction seat is spherical, and the extraction mechanism is provided with a movable mechanism for controlling the movement of the extraction seat.

[0012] Liquid chlorine is transported through a delivery pipeline, and a mounting seat is used to mount an extraction mechanism on the delivery pipeline. A small amount of liquid chlorine in the delivery pipeline is extracted by the extraction mechanism and then delivered to the analysis chamber. The purity of the liquid chlorine is analyzed by the analyzer in the analysis chamber. The extraction mechanism extracts the liquid chlorine and places it in the extraction chamber through the movement of the extraction piston. The extraction seat is then controlled to rotate by the movable mechanism so that the opening of the extraction chamber corresponds to the analysis chamber, thereby transferring part of the liquid chlorine in the extraction chamber to the analysis chamber. The extraction seat is then continued to be rotated so that the opening of the extraction chamber corresponds to the delivery pipeline, and the liquid chlorine in the extraction chamber is discharged through the extraction seat to close the analysis chamber, thereby improving the accuracy of the detection and analysis of the analyzer. The liquid chlorine is quickly transferred to the analysis chamber through the extraction chamber, thereby improving the timeliness of the detection and analysis of the liquid chlorine in the delivery pipeline.

[0013] Furthermore, the activity mechanism includes:

[0014] A rotating shaft is connected to the extraction seat;

[0015] A first drive motor is installed and connected to the rotating shaft, and the first drive motor is used to drive the extraction seat to rotate;

[0016] Wherein, the axis of the rotating shaft is perpendicular to the axis of the extraction chamber.

[0017] The first drive motor drives the rotating shaft to rotate, and the rotating shaft is installed and connected to the extraction seat. By controlling the extraction seat to rotate around the rotating shaft, the opening of the extraction cavity on the extraction seat is rotated corresponding to the inside of the delivery pipe and the analysis cavity.

[0018] Furthermore, the extraction mechanism further includes:

[0019] A first driving cylinder is installed between the extraction seat and the extraction piston;

[0020] An extraction tube, movably mounted on the extraction piston;

[0021] A first connecting channel is placed on the extraction seat;

[0022] a first valve plate, mounted on the first connecting channel;

[0023] a second driving cylinder disposed between the extraction tube and the extraction piston;

[0024] Among them, one end of the extraction tube is connected to the second driving cylinder, and the other end of the extraction tube is provided with an extraction hole, and the extraction hole is hourglass-shaped. The extraction tube is provided with a second connecting channel connected to the first connecting channel, and the extraction tube is provided with a circulation channel, and the circulation channel is connected between the second connecting channel and the extraction hole.

[0025] The extraction piston is driven to move by the first drive cylinder, the extraction tube is movably connected to the extraction piston, and the relative movement between the extraction tube and the extraction piston is controlled by the second drive cylinder. The first valve plate is installed on the first connecting channel. When the analyzer in the analysis chamber completes the purity analysis, the extraction tube is extended from the extraction piston and moved toward the axis of the delivery pipeline. A Venturi effect is formed through the extraction hole and the circulation channel. When liquid chlorine flows through the extraction hole at high speed, negative pressure is generated in the circulation channel and the second connecting channel. When the first valve plate is opened, the liquid chlorine in the analysis chamber is extracted into the delivery pipeline, thereby improving the analysis and detection accuracy in the subsequent analysis chamber. When the liquid chlorine is extracted by the extraction piston, the extraction tube contracts, so that the extraction hole is placed in the extraction piston.

[0026] Furthermore, the extraction tube includes:

[0027] A valve seat, movably connected to the extraction pipe;

[0028] a first spring disposed between the valve seat and the extraction tube;

[0029] a valve body, fixed to the extraction pipe;

[0030] Wherein, the valve seat is installed and connected to the second connecting channel.

[0031] The valve seat and the extraction tube are movably connected. The first spring acts between the valve seat and the extraction tube, so that the valve seat and the valve body are in a closed state. When the extraction tube extends from the extraction piston until the valve seat and the extraction piston are in contact, the valve seat and the valve body are opened, so that the flow channel is connected with the second connecting channel.

[0032] Furthermore, the first valve plate includes:

[0033] An installation shaft is installed and connected with the first valve plate;

[0034] a permanent magnet, mounted on the first valve plate;

[0035] A first electromagnet, corresponding to the permanent magnet and disposed on both sides of the permanent magnet, wherein the first electromagnet is mounted on the extraction seat;

[0036] Wherein, the first valve plate is provided with a flow hole.

[0037] The first valve plate is controlled to rotate around the mounting axis by the first electromagnet and the permanent magnet, so that the flow hole of the first valve plate is opened or closed. The first electromagnet and the permanent magnet are used to increase the speed of opening and closing of the first valve plate. By changing the power supply state of the first electromagnet, the interaction between the first electromagnet and the permanent magnet is changed, thereby controlling the rotation of the first valve plate.

[0038] Furthermore, the activity mechanism also includes:

[0039] Rotating sleeve, movably installed on the conveying pipeline;

[0040] A second drive motor is mounted on the mounting base;

[0041] A first gear is mounted on the output shaft of the second drive motor;

[0042] A second gear is mounted on the rotating sleeve;

[0043] Wherein, the extraction seat, analysis chamber and analyzer are installed on the rotating sleeve.

[0044] The rotating sleeve is installed on the conveying pipeline through a sealed bearing. The rotating sleeve is driven to rotate around the axis by the second drive motor, the first gear, and the second gear. Through the rotation of the rotating sleeve, the extraction seat can be controlled to detect and analyze the purity of liquid chlorine at different positions on the circumference of the corresponding conveying pipeline, thereby further improving the overall purity analysis accuracy of the liquid chlorine in the conveying pipeline.

[0045] Furthermore, the extraction tube is provided with a movable cover, the extraction hole is placed between the movable cover and the extraction tube, and a second electromagnet is provided between the movable cover and the extraction tube.

[0046] Liquid chlorine is extracted from the delivery pipe near the inner wall through the extraction chamber and the extraction piston. When the movable cover is opened by the second electromagnet, the negative pressure in the circulation channel extracts the liquid chlorine. Liquid chlorine near the middle of the delivery pipe can be extracted through the extraction tube, further improving the purity analysis accuracy of the liquid chlorine in the delivery pipe.

[0047] The present application also provides a control method for a liquid chlorine purity analysis device, the specific steps of which include:

[0048] S1, extracting liquid chlorine from the delivery pipeline through the extraction mechanism, and then controlling the extraction seat to rotate through the movable mechanism to align the extraction chamber with the analysis chamber, so that the liquid chlorine in the extraction chamber enters the analysis chamber, and the purity is analyzed by the analyzer;

[0049] S2, when the liquid chlorine in the extraction chamber enters the analysis chamber, the extraction seat is rotated to place the extraction chamber into the corresponding delivery pipe, and the liquid chlorine in the extraction chamber is discharged through the extraction piston;

[0050] S3, after completing the liquid chlorine purity analysis, the extraction pipe is moved toward the delivery pipe until the valve body is opened, and the first valve plate is opened at the same time. When the liquid chlorine flows through the extraction hole, the analysis chamber is vacuumed;

[0051] S4, after the analysis chamber is evacuated, the movable cover is controlled to open, and liquid chlorine near the middle of the delivery pipe is extracted through the extraction tube for purity analysis. After the analysis is completed, the movable cover is reset and the analysis chamber is continued to be evacuated;

[0052] S5, set 8-12 extraction points on the circumference of the rotating sleeve. After completing the extraction of two different positions of the current node, the rotating sleeve rotates to the next extraction point and continues steps S1-S4.

[0053] When liquid chlorine is transported in the delivery pipeline, the extraction seat is controlled by rotating the rotary sleeve to extract liquid chlorine at different points, and the liquid chlorine near the inner wall surface of the delivery pipeline and near the middle part of the delivery pipeline are detected and analyzed respectively, thereby improving the detection and analysis accuracy of the comprehensive purity of the liquid chlorine in the delivery pipeline and having high timeliness. The liquid chlorine after detection is returned to the delivery pipeline, thereby improving resource conservation.

[0054] The beneficial effects of this application are:

[0055] 1. A small amount of liquid chlorine in the delivery pipeline is extracted by the extraction mechanism and then delivered to the analysis chamber. The purity of the liquid chlorine is analyzed by the analyzer in the analysis chamber, and the liquid is quickly transferred to the analysis chamber through the extraction chamber, which can improve the timeliness of the detection and analysis of liquid chlorine in the delivery pipeline.

[0056] 2. The extraction mechanism extracts the liquid chlorine into the extraction chamber by moving the extraction piston, and then controls the rotation of the extraction seat through the movable mechanism so that the opening of the extraction chamber corresponds to the analysis chamber, thereby transferring part of the liquid chlorine in the extraction chamber to the analysis chamber.

[0057] 3. After the analyzer in the analysis chamber completes the purity analysis, the extraction tube is extended from the extraction piston and moved toward the axis of the delivery pipeline. When the first valve plate is opened, the liquid chlorine in the analysis chamber is extracted into the delivery pipeline through the extraction tube, thereby improving the accuracy of subsequent analysis and detection in the analysis chamber.

[0058] 4. By rotating the rotating sleeve, the extraction seat can be controlled to detect and analyze the purity of liquid chlorine at different positions on the circumference of the corresponding delivery pipeline, further improving the overall purity analysis accuracy of liquid chlorine in the delivery pipeline.

The extraction chamber 320 is placed on the extraction seat 310. The extraction piston 330 is placed on the extraction seat 310 and corresponds to the extraction chamber 320. The extraction seat 310 is spherical. The extraction mechanism 300 is provided with a movable mechanism 500 for controlling the movement of the extraction seat 310.

[0077] Liquid chlorine is transported through the delivery pipe 100. The mounting base 200 is used to mount the extraction mechanism 300 on the delivery pipe 100. A small amount of liquid chlorine in the delivery pipe 100 is extracted by the extraction mechanism 300 and then transported to the analysis chamber 400. The purity of the liquid chlorine is analyzed by the analyzer 410 in the analysis chamber 400. The extraction mechanism 300 moves the extraction piston 330 to extract the liquid chlorine and place it in the extraction chamber 320. Then, the extraction base 310 is controlled to rotate by the movable mechanism 500 to make the extraction chamber 320 empty. The opening of 20 corresponds to the analysis chamber 400, so that part of the liquid chlorine in the extraction chamber 320 is transferred to the analysis chamber 400, and then the extraction seat 310 is continued to be rotated so that the opening of the extraction chamber 320 corresponds to the conveying pipe 100, and the liquid chlorine in the extraction chamber 320 is discharged through the extraction seat 310 to close the analysis chamber 400, thereby improving the accuracy of the detection and analysis of the analyzer 410, and quickly transferring it to the analysis chamber 400 through the extraction chamber 320, which can improve the timeliness of the detection and analysis of the liquid chlorine in the conveying pipe 100.

[0083] The first drive motor 520 drives the rotating shaft 510 to rotate. The rotating shaft 510 is installed and connected to the extraction base 310. By controlling the extraction base 310 to rotate around the rotating shaft 510, the opening of the extraction chamber 320 on the extraction base 310 is rotated corresponding to the inside of the delivery pipe 100 and the analysis chamber 400.

[0084] Example 3:

The extraction tube 350 is provided with a second connecting channel 370 connected to the first connecting channel 311, and the extraction tube 350 is provided with a circulation channel 352, and the circulation channel 352 is connected between the second connecting channel 370 and the extraction hole 351.

[0092] The extraction piston 330 is driven to move by the first driving cylinder 340. The extraction pipe 350 is movably connected to the extraction piston 330. The relative movement between the extraction pipe 350 and the extraction piston 330 is controlled by the second driving cylinder 360. The first valve plate 312 is installed on the first connecting channel 311. When the analyzer 410 in the analysis chamber 400 completes the purity analysis, the extraction pipe 350 is extended from the extraction piston 330 and moved toward the axis of the delivery pipeline 100. A Venturi effect is formed through the extraction hole 351 and the circulation channel 352. When liquid chlorine flows through the extraction hole 351 at a high speed, a negative pressure is generated in the circulation channel 352 and the second connecting channel 370. When the first valve plate 312 is opened, the liquid chlorine in the analysis chamber 400 is extracted into the delivery pipeline 100, thereby improving the accuracy of subsequent analysis and detection in the analysis chamber 400.

The first spring 354 acts between the valve seat 353 and the extraction pipe 350, so that the valve seat 353 and the valve body 355 cooperate to be in a closed state. When the extraction pipe 350 extends from the extraction piston 330 until the valve seat 353 and the extraction piston 330 are in contact with each other, the valve seat 353 and the valve body 355 are opened, so that the circulation channel 352 is connected with the second connecting channel 370.

The first electromagnet 315 and the permanent magnet 314 are used to increase the speed of opening and closing of the first valve plate 312. By changing the power supply state of the first electromagnet 315, the interaction between the first electromagnet 315 and the permanent magnet 314 is changed, thereby controlling the rotation of the first valve plate 312.
